EXPLANATIONS BELOW
Concept note-1: -The Truman Doctrine demonstrated that the United States would not return to isolationism after World War II, but rather take an active role in world affairs. To help rebuild after the war, the United States pledged $13 billion of aid to Europe in the Marshall Plan.
Concept note-2: -With the Truman Doctrine, President Harry S. Truman established that the United States would provide political, military and economic assistance to all democratic nations under threat from external or internal authoritarian forces.
Concept note-3: -How was American involvement in Vietnam an extension of the Truman Doctrine? The Truman Doctrine stated that the United States should intervene to prevent, or contain, the spread of communism. The United States entered the Vietnam War to prevent communism from spreading in Southeast Asia.
Concept note-4: -The reaction to Truman’s speech was broadly positive, though there were dissenters. Anti-communists in both parties supported both Truman’s proposed aid package and the doctrine behind it, and Collier’s described it as a “popularity jackpot” for the President.
Concept note-5: -Fanned by the fear of Communist expansion and the rapid deterioration of European economies in the winter of 1946–1947, Congress passed the Economic Cooperation Act in March 1948 and approved funding that would eventually rise to over $12 billion for the rebuilding of Western Europe.
